Supercontinent Cutout.

Analysis Questions:

1. What are 3 pieces of evidence you used to fit together the continents?

Cutout the continents and fit them together to make the supercontinent that Wegener proposed. Glue them on this page.

2. Why is this called a supercontinent?

3. How does this model help support the Theory of Continental Drift?

4. Why aren’t the continents still in this location today?

In Wegener’s time, his theory was ridiculed.

Why do you think that many scientists initially rejected the idea of continental drift?

Thurs. 2/21 and Fri. 2/22

• Prior to Alfred Wegener’s theory of continental drift geologists thought continents were fixed in their locations. In developing his theory which of the following evidence was NOT used by

Wegener?

a) Fossil similarities between southern continents.

b) Evidence of polarity change in found along the Mid-

Atlantic Ridge.

c) Similarities in the paleoclimates of South America and Africa.

d) The apparent fact the South America and Africa seemed to fit together.

As you travel towards the center of the Earth, the temperature increases because of heat generated by the core.

Before reading:

What makes the heat at the Earth’s core?

Why is the core so hot?

• It's a combination of radioactivity (the radioactive materials in the Earth generate heat) and the residual heat from the formation of the Earth. When all of the matter that created the Earth fell together, it picked up kinetic energy falling in. When it stopped at the proto-Earth, the kinetic energy was turned into heat. The Earth hasn't cooled yet. But, the vast majority of the heat in Earth's interior—up to 90 percent—is fueled by the decaying of radioactive isotopes like Potassium 40, Uranium 238, 235, and

Thorium 232 contained within the mantle. These isotopes radiate heat as they shed excess energy and move toward stability. "The amount of heat caused by this radiation is almost the same as the total heat measured emanating from the Earth."

The Lithospheric Plates

The crust of the Earth is broken into many pieces called plates . The plates "float" on the soft, semi-rigid

asthenosphere.

The Asthenosphere

The asthenosphere is the semi-rigid part of the middle mantle that flows like hot asphalt under a heavy weight.

Convection Currents

The middle mantle "flows" because of convection currents. Convection currents are caused by the very hot material at the deepest part of the mantle rising, then cooling and sinking again --repeating this cycle over and over.

Convection Currents

The next time you heat anything like soup or water in a pan you can watch the convection currents move in the liquid. When the convection currents flow in the asthenosphere they also move the crust. The crust gets a free ride with these currents, like the cork in this illustration.
